How do master key systems work?
A master key system is a single set of locks rekeyed so each lock has its own change key, plus one or more master keys that open multiple locks. Your Knightdale, NC commercial locksmith designs the hierarchy to match your access policy.
Each lock has its own pin stack. A master key system uses extra master pins inside each cylinder so two different keys (the change key and the master key) both turn the lock. More tiers can be added — grand master, sub-master, change key.
A typical office in Knightdale, NC might have a master key for owners, sub-masters for managers, and change keys for individual offices. Your Knightdale, NC commercial locksmith plans the hierarchy and documents which keys open which doors.
Master key systems are easy to expand or restructure later. If a key is lost or someone leaves the company, your Knightdale, NC locksmith rekeys only the affected level — not every door.
